Some fourth order CY-type operators with non symplectically rigid monodromy
Bogner, Michael · Reiter, Stefan
Original · EN
We study tuples of matrices with rigidity index two in ₄(C), which are potentially induced by differential operators of Calabi-Yau type. The constructions of those monodromy tuples via algebraic operations and middle convolutions and the related constructions on the level differential operators lead to previously known and new examples.
